I think JDAW has been trying to get this list. Doesn't have number of bottles but does say what they have. Scroll down toward bottom for the Ports. Some of those they need to drink sooner rather than later. And they got 1931 Noval

Is this cellar run by someone who knows something about wine? - or some unknown buggins from the department for straightening paperclips..

Having been a Civil Servant for two decades (two decades ago) I suspect their wine supplier (BBR?) provides expert advice at huge cost to the tax payer and then some jobsworth with a spreadsheet and a qualification in buying wine from Aldi uses his expertise to refine that advice and make bad decisions.

When the Beast of Bolsover finally retires I might put myself forward as MP for my constituency simply to get my hands on those pre-50s bottles

According to the papers filed by the Home Office, the cellar is overseen by a committee of three masters of wine under the chairmanship of Sir David Wright, a former ambassador. None are paid for their work on the committee. The objective of the cellar is to supply wines to government functions and to sell sufficient stock onto the open market (through Christie's) to cover the costs of purchases made during the year. For example, in 2015-16 the cellar sales included 36 bottles of Graham 1983 and 24 bottles of Warre 1985. From what they publish, it seems this objective has been met in each of the last 4 years for which papers have been made public. In 2015-16 the committee spent £40,177 on new stock and raised £40,390 from sales of existing holdings.
